Just picked this bad boy up because I needed a display that would do 4k over HDMI at 60hz and had HDR and all the bells and whistles needed for the Xbox One X to allow all the available display modes (minus 3d). I ended up also using it as a second display for my PC and there is no mouse lag and its 4k at 60hz. Really a sweet TV and super cheap. Price is reflected in the cart and only available in store. $ 100 cheaper than Amazon: https://www.amazon.com/dp/B074NFW…ZFARYF50TW and $ 130 cheaper than Costco: https://www.costco.com/Samsung-40…54118.html
